Flow Master 2 Chamber Catback

[meade01]

I have a 2003 GT with SLP catback and a upr offroad x pipe and i'm thinking about switching to a 2 chamber flow master catback, because the present combo is so loud. I would like to know would the flow master setup be quieter?

Which SLP catback do you have?. I'm assuming the LMIs. If so then yes, the flowmasters would defiantly be a lot quieter.
